What are the Symptoms of Bell's Palsy
Here is a list of common symptoms of Bell's Palsy:
- Sudden weakness or paralysis on one side of the face may make it difficult to close the eye or smile.
- Drooping of the mouth or eyelid on the affected side, affecting facial expression.
- Facial muscle twitching or stiffness.
- Altered taste, increased sensitivity to sound on one side, or tear or saliva production changes.
- Pain around the jaw or behind the ear on the affected side.
- Difficulty closing the eye, leading to dryness or irritation.
- In severe cases, complete facial paralysis on the affected side.
- Common symptoms in newborns include lack of movement on one side of the face, which may indicate birth trauma or nerve injuries.
Diagnosing and Treating Bell's Palsy
A diagnosis of Bell's Palsy starts with a comprehensive medical evaluation, during which a medical professional examines the facial muscles and nerve function. This examination often includes assessing the patient's ability to perform facial expressions and testing sensation across different face areas. Alongside this physical evaluation, the doctor reviews the patient's medical history, paying special attention to any recent viral infections or vaccines that might point to potential causes of the condition.
In certain cases, imaging tests like MRI or CT scans are employed to exclude other possible causes of facial nerve damage, such as tumors or strokes. Additionally, electromyography (EMG) is crucial in the diagnostic process. This test measures the electrical activity in the facial nerves, providing valuable insights into the extent of nerve damage, which is essential for making an effective treatment plan.
